(8/9) x = 64
\n" ); document.write( "8x/9=64
\n" ); document.write( "8x=9*64
\n" ); document.write( "8x=576
\n" ); document.write( "x=576/8
\n" ); document.write( "x=72 ans.
\n" ); document.write( "Proof:
\n" ); document.write( "(8/9)72=64
\n" ); document.write( "8*8=64
\n" ); document.write( "64=64
\n" ); document.write( "OR:
\n" ); document.write( "(8/9x)=64
\n" ); document.write( "9x*64=8
\n" ); document.write( "576x=8
\n" ); document.write( "x=8/576
\n" ); document.write( "x=1/72 ans.
\n" ); document.write( "Proof:
\n" ); document.write( "8/(9*1/72)=64
\n" ); document.write( "8/(9/72)=64
\n" ); document.write( "8*72/9=64
\n" ); document.write( "8*72=9*64
\n" ); document.write( "576=576 \n" ); document.write( "

\n" );
